SWING.

SPECIFICATION forming part of Letters Patent No. 431,260, dated July 1,1890.

', Application filed November 12, 1889. $erial No. 329,981. (No model.)

To all whom it may concern.-

Be it known that I, JOHN HANNEN, of Chicago, in the county of Cook andState of Illinois, have invented a new and Improved Swing, of which thefollowing is a full, clear, and exact description.

Myinvention relates to that class of swings vin which suspension-rodsinstead of ropes are used; and the object of my invention is to providea safe and comfortable swing that will occupy but little space and thatcan be easily operated by the person swinging.

To this end myinvention consists in a movable pyramidal frame having twoswinging suspension-rods carrying a slightly-tilting spring-seat andattached to said frame near the top.

The details of this construction will be hereinafter fully explained,and more specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is afront elevation of a swing embodying my invention, and Fig.2 aside elevation of the same.

The frame A consists of four standards which meet at the top, where theyare firmly fastened together by the key across-ties, and bolts. Thestandards slope outwardly toward the base of the frame, forming the fourcorners thereof, and at the bottom they are firmly connected by thecross-bars or sills B and B, which constitute the base of the frame.

Upon two opposite sides of the frame A, near the top, are cross-piecesb, which are securely attached to the sides of the frame and providedwith ears 0, to which is secured the shaft (1. The shaft (1 extendsacross from one cross-piece b to the other, and from it is suspended theswing proper.

The side pieces or suspension-rods D of the swing are provided at theextreme top with metal plates 6, which turn upon the shaft (Z, and thuscause less wear and friction than would be the case if the wooden rods Dwere attached directly to the shaft. The plates 6 are prevented fromsliding on the shaft d by the collars 6, attached to the shaft on eachside of the swing. The side pieces D are securely braced and arefastened together at the seat being supported by a spring f, one

end of which is attached to the seat and the other to the side piecesbelow the seat. Just below the back part of the seat and attached toeach side piece is a rest g, to prevent the seat from falling if thespring f should break. At a convenient distance above the seat the sidepieces D are provided with handles h, to be grasped by the personswinging.

One of the standards of the frame A should be provided with cleats 7',which serve as a ladder, 'up which a person may climb to oil thebearings at the top.

To set and keep the swing in motion, the person swinging simply leansbackward in the swing. This causes the seat to tip, and by changing thecenter of gravity imparts a forward movement to the swing. By repeatingthis action the swing may be kept in motion and forced to any desiredheight.

Having thus described my invention, what I claim as new, and desire 'tosecure by Letters Patent, is

1. The combination, with the suspensionrods of a swing, of a seatpivoted near its front edge between and to the said rods, and stopssecured to the suspension-rods below the seat and projecting rearwardlyto limit the downward movement of the seat, substantially as described.

2. The combination, with the suspensionrods of a swing,'of a seatpivoted between the rods at one side of its center, and a spring securedto the rods and to the seat, and a stop secured to each rod below theseat, substantially as herein shown and described.

3. A swing consisting, essentially, of the movable pyramidal framecomposed of the standards A and sills B B, the cross-pieces I), attachedto said frame, the shaft (Z, supported upon said cross-pieces, the sidepieces D,suspended from said shaft, the pivoted seat E, handles h,spring f, and rest all'arranged substantially as shown and described.

JOHN HANNEN.
